The design of PopUp was driven by an idea of movement and transcience. Barcelona's harbor is a space defined by movement and acts as a nexus between the city and the sea. PopUp seeks to capture and facilitate this movement around the site, while visually generating movement within the site. The architecural elements of PopUp arose from movement on and around the site as well as the need to minimize its impact on the site as a temporary structure. PopUp Pavilion Consists of two components: 1. A series of lightweight aluminium structures with locking hinged frames that are enveloped by a perforated, translucent fabric. 2. A riased module platform which accomodates the programmatic requirements and circulation. PopUp can be pre-fabricated and shipped to the site, where assembly (and disassembly) can be completed in minimal time without harming the original state of the site. Inspired by "pop-up" cards, the aluminum structures are sheathed by a lightweight translucent fabric from a flat position, then raised 90 degrees and locked into place as a rigid frame. The frames are then placed on the modular platforms completing the assembly.
